+Subject: [PATCH] Require cmake >= 3.1.2 (for correct openssl 1.0.2 detection)
+
+@ygj6 reported:
+  "My platform is MacOS 10.13.5, This problem only happens on Mac.
+
+   As written in the file CMakeLists.txt, the minimum required version of cmake is 3.1:
+     cmake_minimum_required(VERSION 3.1 FATAL_ERROR)
+   So I built this project with cmake-3.1.0, but I got the following errors:
+
+       CMake Error at /usr/local/cmake-3.1.0/share/cmake/Modules/FindOpenSSL.cmake:293 (list):
+         list GET given empty list
+       Call Stack (most recent call first):
+         CMakeLists.txt:824 (find_package)

+       CMake Error at /usr/local/cmake-3.1.0/share/cmake/Modules/FindOpenSSL.cmake:296 (list):

+       CMake Error at /usr/local/cmake-3.1.0/share/cmake/Modules/FindOpenSSL.cmake:298 (list):
+         list GET given empty list
+       Call Stack (most recent call first):
+         CMakeLists.txt:824 (find_package)
+
+   I googled this error and got this answer:
+     https://bugs.archlinux.org/task/43688
+
+   It is a bug in FindOpenSSL.cmake on cmake-3.1.0 and fixed on cmake-3.1.2 .
+   Of course, It was successful when rebuilding with cmake-3.1.2 .
+   So I suggest setting the minimum version required for cmake to 3.1.2 or higher.

+Subject: [PATCH] Make dependency paths relocatable
+
+The generated configurations for both CMake and pkg-config included
+absolute paths to dependencies (OpenSSL, MbedTLS). This is contrary
+to the general CMake advise to create relocatable packages [1].
+
+Additionally, when building both mbedtls and libevent via CMake's
+FetchContent in the same project, loading the project would fail with
+
+  INTERFACE_INCLUDE_DIRECTORIES property contains path:
+    "/home/user/project/cmake-build/_deps/mbedtls-build/include"
+  which is prefixed in the source directory.
+
+The required changes include:
+- Adding the outer includes only to the BUILD_INTERFACE solves the
+  makes the CMake paths relocatable and thus solves the FetchContent
+  problem.
+- Updates to libevent_*.pc.in fixes the relocatable issues for
+  pkg-config and properly declares currently missing dependencies.
+- Using components for linking to OpenSSL (requiring CMake 3.4)
+  and MbedTLS. The new MbedTLS target names now match the component
+  names of the MbedTLS' CMake project.
+- Use the Threads CMake library reference instead of a direct
+  reference to support both built-in pthread and -lpthread.
+
+v2 (azat): get back CMAKE_REQUIRED_LIBRARIES
